This will sound stupid?

So my girlfriend has been playing "Minecraft" a video game i'm sure your familiar with and I'm in a weird situation that I don't know how to take. So basically she plays a lot on this multiplayer server where other players are online at the same time and she is friends with them. She has a pretty high role on there and has a lot of ingame currency as do the other top players on the server which are all friends. There's a marriage feature in the game where you can marry another player and basically all the top players were in couples expect for her and this other guy, which she claims is a woman but other things say its a man, its all very weird. Basically when your married in the server you get a heart emoji next to your name and thats what she wanted apparently, not because she is marrying this guy in a video game. So she requested to marry him and he excepted and then she got her heart. How am I suppost to react to this?

I wouldnt worry about it, its just a game

It's a game, chill unless you want to look like an idiot.

You got to be a little *** kid

Unless her gameplay takes so much time away from your relationship that you're feeling left out this is probably just good, clean fun. As long as she never suggests meeting this person IRL you can probably just assume it's part of the game and not a big deal.

You're not supposed to "react" to it at all - there's nothing to "react" to. It's nothing more than a video game with a lot of different players. She's not really "marrying" one of them. She's playing an online game with a bunch of people she's never met and whom she will never meet.
